Those conditions do not provide much incentive for the North Koreans to try and have talks with the US.
Regarding the North's Sunday test of an intermediate-range ballistic missile, Harris said it posed a threat to not only the Korean Peninsula, but also to Japan, China, Russia, the USA and beyond.
Xi told Moon's representative Lee Hae-chan on Friday that his visit showed the importance the new South Korean leader attached to relations with Beijing.
US Ambassador to the UN Nikki Haley said the United States was working with China on a new sanctions resolution and warned that all countries must step up action against North Korea or face measures themselves.
North Korea has made no secret of its work to develop a nuclear-tipped missile capable of striking the United States and has ignored calls to halt its nuclear and missile programmes, even from China, its lone major ally.
In the song, group members chant that "about THAAD we say no, no, no", a reference to the U.S. Army's missile defense system formally known as Terminal High Altitude Area Defense.
On North Korea, which test-fired its latest ballistic missile into the Sea of Japan over the weekend, Abe said Japan, South Korea and the United States should increase pressure on the reclusive country.
Chinese official media quoted Xi as saying China is committed to resolving any issues through dialogue and coordination.More news: Ronald Koeman still waiting for update on Ross Barkley's Everton future

Chinese Foreign Minister Wang Yi met Thursday with a special envoy from President Moon Jae-in as the two countries seek to mend frayed ties over the deployment of a Terminal High-Altitude Area Defense battery from the US here.
President Moon said the country will maintain its current sanctions on North Korea, and respond sternly against any provocations by maintaining a strong South Korea-U.S. alliance, and by beefing up the South's own military capabilities, including the development of the Korea Air and Missile Defense System.
Despite Han's seemingly reassuring comment that the THAAD system, which is placed on a golf course in Seongju county in southern South Korea, was able to track the missile, there are serious limitations as to what the system can do against a missile like the Hwasong-12.
Lee earlier told reporters in Beijing that Moon hopes to sit down with Xi on the sidelines of the G20 Summit in Germany in July as well as on August 24, which marks the 25th anniversary of bilateral relations.
Russian Federation and China have opposed the THAAD deployment, calling on the all parties to find a peaceful solution to the hazardous situation in the region.
Moon has sent envoys to the United States, China, Japan and the European Union this week in what the government has called "pre-emptive diplomacy".
Moon Jae-in, who easily won South Korea's presidential election Tuesday, was the beneficiary of another popular backlash against a ruling establishment perceived as corrupt and out of touch.
